This invokes a wizard that will walk you step by step through a process of subscribing recipients from a file or set of files. This command does not add or delete recipients to the list it just makes them active (enabled). The recipients should already exist in the list. You can use Import feature to add new recipients to mailing list.

You can subscribe the recipients from files containing only email addresses or files with all the fields like Name, Title, Address and so on. On the first page of the wizard you should choose one of those options and press next. On the next page of the wizard you should choose whether you want to subscribe recipients from a single file that you produced from your subscriber database or from a set of files contained in one folder. Make a choice and press next.
